How to Quickly check FSMO roles

How to Quickly check FSMO roles

Active Directory contains five roles called Flexible Single Master Operation Roles (FSMO), these roles are required for the domain controllers to function correctly. During the first domain controller installation, the FSMO roles are installed automatically. In most cases they can be left alone, but there are times when they need to be moved such as a failed DC.

It is a good idea to be familiar with where the roles are installed in your AD environment, you never know when a disaster will hit. In this post, I will walk through two simple methods for finding the roles.

The first method uses the Netdom query tool and the second uses windows GUI mode.

Netdom query tool 

Forest Wide Roles: Schema Master, Domain naming master

Domain Wide Roles: PDC, RID manager, Infrastructure Master

Method #2: Use the GUI

The FSMO role holders can be easily found by use of some of the AD snap-ins.

Use this table to see which tool can be used for what FSMO role:  

To find out who currently holds the Domain-Specific RID Master, PDC Emulator, and Infrastructure Master FSMO Roles:

• Open the Active Directory Users and Computers snap-in from the Administrative Tools or run the DSA.msc .
• Right click on WindowsTechno.local and click on Operation Masters. 

• Select the appropriate tab for the role you wish to view.

RID Master 

PDC Emulator-

Infrastructure Master

• When you’re done click Close.

Finding the Domain Naming Master via GUI To find out who currently holds the Domain Naming Master Role:

• Open the Active Directory Domains and Trusts snap-in from the Administrative Tools folder.

• Right-click the Active Directory Domains and Trusts icon again and press Operation Masters.

Finding the Schema Master via GUI To find out who currently holds the Schema Master Role:

• Run regsvr32 schmmgmt.dll from an elevated command prompt

•  Run mmc.exe
• In the empty console that opens add the Active Directory Schema  Management snap-in.
• Right click on the Schema icon and select Operations Master.

This will show you who currently holds it and allow you to transfer it.  

For more information around FSMO Roles, review:

• Schema Master
• Domain Naming Master
• Infrastructure Master
• Relative ID (RID) Master
• Primary Domain Controller (PDC) Emulator
